we have those structures, but *don't* define them if we have
TERMIOS, whose functions take care of those parameters; that
screws up AIX.
(struct emacs_tty): Test those symbols, instead of the ioctl
commands.
* sysdep.c (emacs_get_tty, emacs_set_tty, new_ltchars, new_tchars,
init_sys_modes): Same.
* s/template.h: Mention that you should #define HAVE_TERMIO or
HAVE_TERMIOS, but not both, and that HAVE_TERMIOS is preferred.
* systty.h (EMACS_SET_TTY_PGRP): Don't assign the return value of
tcsetpgrp to *pgid; it's just a status value.
* config.h.in (HAVE_RANDOM): This shouldn't be defined on Linux
systems using XFree386, and perhaps is inappropriate in general.
* m/intel386.h: #undefine the integer size macros, since the Linux
<values.h> file #defines them itself.
* mem-limits.h (get_lim_data): Linux has the ulimit call; if it
fails, fall back on ULIMIT_BREAK_VALUE.
* process.c: Linux needs the WAITTYPE, etc. definitions.
* unexec.c (hdr, ohdr): Linux has the ordinary `struct exec' type;
no need to use SYSV names.
* s/linux.h: New file.
* sysdep.c (sys_siglist): Don't define this if HAVE_SYS_SIGLIST is
#defined. That lets the system provide it, if it has it.
* syssignal.h (sigmask): Only define this if <signal.h> hasn't
given us a definition already.
* syssignal.h (sys_sigpause): Fix argument in prototype.
* sysdep.c (init_signals): The masks are called empty_mask and
full_mask, not signal_empty_mask and signal_full_mask.
(signal_handler_t): Moved ....
* syssignal.h: ... to here.
* systty.h (EMACS_SET_TTY_PGRP): Call tcsetpgrp with the correct
arguments.
* emacs.c (main): Don't try to establish signal handlers for
SIGBUS and SIGSYS unless they're actually #defined.
* systty.h [HAVE_TERMIO, __DGUX]: #include <sys/ioctl.h>.
* [VMS] systime.h: Include vmstime.h. VMS has the timezone
variable and the tzname array.
* s/vms.h: VMS does have select.
mth$dmod is the same as Unix's drem.
Use the time functions in vmstime.c.
No need to rename the malloc routines if we're using GNU malloc.
PURESIZE needs to be 330000.
* vmstime.c, vmstime.h: New files.
* systty.h: Don't try to initialize extern declarations under VAX C.
* vmspaths.h (PATH_LOADSEARCH): Include EMACS_LIBRARY:[LOCAL-LISP]
in PATH_LOADSEARCH.
(PATH_EXEC): Use EMACS_LIBRARY:[LIB-SRC] instead of [ETC].
* sysdep.c [VMS] (init_sys_modes): Don't allocate process_ef.
[VMS] (queue_kbd_input): Build events structure correctly.
[VMS] (gethostname): New function.
[VMS] (getwd): Don't get the PATH environment variable; that's
dumb. Call getcwd.
